Thirty teams, thirty ballparks — but 2026 has one exception worth knowing before you plan a stadium road trip. Here's the exact count, the divisional breakdown, and the one team currently playing home games somewhere unexpected.
There are 30 MLB stadiums in 2026, one for each of the league's 30 teams, split evenly between the American League and National League. The catch: the Oakland Athletics don't have a true MLB-caliber home right now — they're playing at Sutter Health Park, a minor league facility in West Sacramento, while their permanent Las Vegas ballpark gets built. So the "30 stadiums" figure includes one team in a temporary park, not 30 purpose-built major league venues.
- 30 MLB stadiums serve the league's 30 teams in 2026 — 15 in the American League, 15 in the National League.
- Fenway Park, opened in 1912, is the oldest ballpark still hosting games; Wrigley Field (1914) is second.
- The Athletics play at Sutter Health Park, a minor league stadium in West Sacramento, while their Las Vegas park is under construction.
- Six divisions of five teams each make up MLB's stadium map, three per league.
- A printable MLB ballpark checklist turns this count into a trip-planning tool for tracking every park you visit.
Why this matters
If you're building a ballpark road trip or checking parks off a bucket-list checklist, the stadium count isn't just trivia — it determines the actual scope of the project. Thirty stops is a very different multi-year plan than the 32-stadium NFL circuit or the 30-arena NBA and NHL slates people often confuse it with. Getting the number right, and knowing which team is in a non-standard home, keeps your itinerary accurate.
How many MLB stadiums are there in 2026?
MLB fields exactly 30 teams, and in 2026 that means 30 stadiums, one per team. No team currently shares a home park, and no city hosts two MLB clubs under one roof. The league splits cleanly into two 15-team conferences, each broken into three five-team divisions:
| League | Division | Teams | Stadiums |
|---|---|---|---|
| American League | East | 5 | 5 |
| American League | Central | 5 | 5 |
| American League | West | 5 | 5 |
| National League | East | 5 | 5 |
| National League | Central | 5 | 5 |
| National League | West | 5 | 5 |
That's six divisions of five teams, 30 teams total, and 30 stadiums to match. The only asterisk is the Athletics, counted here as one of the 30 even though Sutter Health Park is a minor league venue rather than a purpose-built MLB stadium.
American League: 15 stadiums
The AL's 15 stadiums stretch from Fenway Park in Boston (1912) to modern builds like Globe Life Field in Arlington, home of the Texas Rangers since 2020. The AL West includes the Athletics' temporary Sutter Health Park situation, which is the one true outlier in the entire 30-park map.
National League: 15 stadiums
The NL's 15 parks include Wrigley Field in Chicago (1914), the second-oldest stadium still hosting MLB games, and Truist Park in Atlanta, which opened in 2017 as one of the newer builds in the league. The NL has no temporary or displaced franchises in 2026 — all 15 teams play in their standard home parks.
Why the MLB stadium count varies year to year
The 30-stadium figure isn't permanent architecture — it shifts for a handful of predictable reasons:
- Franchise relocations. The Athletics' move from Oakland to a temporary Sacramento home, ahead of a planned Las Vegas stadium, is the clearest 2026 example.
- New stadium construction. Teams periodically replace aging parks (Globe Life Field replaced Globe Life Park in 2020, Truist Park replaced Turner Field in 2017), which changes the physical building but not the team count.
- Renovations that temporarily relocate a team. Extensive rebuilds can push a franchise into a secondary or minor league park for a season or more.
- Spring training facilities don't count. Cactus League and Grapefruit League ballparks are separate from the 30 regular-season stadiums and shouldn't be added to the total.
- Minor league and independent league parks don't count either. Only the 30 stadiums hosting regular-season MLB games belong in this figure, even when a team like the Athletics is temporarily using a minor league facility.

One last thing
The number that trips people up isn't 30 — it's the fact that one of those 30 isn't really a major league stadium at all right now. Sutter Health Park seats far fewer fans than a standard MLB park, and it's a detail every serious ballpark-hunter needs to know before checking Oakland's old home off a list that no longer applies. Build your 2026 itinerary around where teams actually play, not where they used to.
